[Quick top post I'm afraid.]

I think that I figured out why there is a problem even earlier
--that just did not stop the compiles.

lib/libutil/kinfo_getallproc.c is built here as part of buildworld
(stage 4.2 "building libraries" instead of buildkernel. It does not
have the KERNCONF's AIM vs. BOOKE vs. . . . definitions vs. lack of
them).

So if it includes machine/pmap.h that binds to
sys/powerpc/include/pmap.h which has the structure. . .

. . .
#if defined(AIM)
. . . (definitions here)
#elif defined(BOOKE)
. . . (definitions here)
#endif
. . .

it gets no definition now.

With the older:

. . .
#if defined(AIM)
. . . (definitions here)
#else
. . . (definitions here)
#endif
. . .

It got a definition, just not necessarily the right one.

(Later quotes are not from the list or from E-mail but from files.)

I'm not targeting BOOKE but GENERIC64 (via include, with AIM but not
ps3). I'm at head -r308860 yet for TARGET_ARCH=powerpc64 I get the
following that did not happen with my older -r308247 builds:

It is almost like a machine/pmap.h include is missing now so that the
types are not defined. But I've not yet found where the relevant
difference(s) are from -r308247.

Showing a compile command (with -v) with its failure. . .

This is a powerpc64-xtoolchain-gcc based cross build:
(I build with libc++ capable materials, not with gcc 4.2.1 .)
